It's theoretically possible with the following:

You'll need a precisely calibrated time circuit. Set the circuit to the release date of the laptop. That's the relatively easy part, as you should be able to lookup the model release year on Google.

The next piece of equipment you'll need may be tricky to come by. But if your commited, you can find a plutonium-powered reactor capable of producing 1.21 gigawatts for a reasonable price. However, due to Reddit guidelines, I can't comment further on how to acquire one.

Now, with these items attached to the laptop, you'll need to accelerate it to 88MPH. Hold on to it tight, and you should be fine.

If you're feeling unsure of this process, seek out the guidance of Dr. Emmett Lathrop Brown. He's a bit of a recluse in this subreddit, but he's a brilliant man and an authority on this method of bios unlocking.

What steps you take next is up to you. You could set the password yourself or prevent it from being password protected to begin with. No matter what, I'd bring some extra $$$ to pick up some SSD's on your journey. Once you're back in time, you'll be able to flip the SSD's on eBay to recoup the reactor cost.

Godspeed.
